What is the structure of long bone?

What is the structure of long bone?

A long bone has two parts: the diaphysis and the epiphysis. The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The hollow region in the diaphysis is called the medullary cavity, which is filled with yellow marrow.

What is the shaft of a long bone called?

medullary cavity. The shaft of a long bone is called the diaphysis.

What is the gross structure of an adult long bone?

Gross Anatomy of Bone A long bone has two parts: the diaphysis and the epiphysis. The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The hollow region in the diaphysis is called the medullary cavity, which is filled with yellow marrow.

How many bone types are there?

The bones of the body come in a variety of sizes and shapes. The four principal types of bones are long, short, flat and irregular. Bones that are longer than they are wide are called long bones.

What is the spongy bone called?

Cancellous bone, also called trabecular bone or spongy bone, light, porous bone enclosing numerous large spaces that give a honeycombed or spongy appearance. The bone matrix, or framework, is organized into a three-dimensional latticework of bony processes, called trabeculae, arranged along lines of stress.

What is a diaphyseal?

The diaphysis is the main or midsection (shaft) of a long bone. It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat). It is a middle tubular part composed of compact bone which surrounds a central marrow cavity which contains red or yellow marrow.

What are the parts of the long bone?

A long bone is made up of three parts: the epiphysis, diaphysis and the metaphysis. A long bone is a cylindrical elongated bone as seen in the femur, or thigh bone; and the humerus, or upper arm bone.

What is an example of a long bone?

Though different long bones have different shapes and functions, they all have the same general structure. Examples of long bones include the femur, tibia, radius and ulna.

What is long bone anatomy?

Anatomical terms of bone. The long bones are those that are longer than they are wide. They are one of five types of bones: long, short, flat, irregular and sesamoid. Long bones, especially the femur and tibia, are subjected to most of the load during daily activities and they are crucial for skeletal mobility.

What is the cross section of the human body?

A transverse plane , also known as an axial plane or cross-section, divides the body into cranial and caudal (head and tail) portions. A sagittal plane divides the body into sinister and dexter (left and right) portions.
